I'd be inclined to say that almost all of DX and IQ! are learned, and fairly consciously learned at that, because they are almost all about skill levels, and even default skills are something you need to be taught. The Will and Per components of IQ are probably more genetic or environmental.

I'm not sure what you would want to know for though. It wouldn't matter to any individual character particularly, and couldn't usually be separated anyway.
